DCX123JK-7-F

Overview

The DCX123JK-7-F is a dual complementary pre-biased transistor in an SOT26 package. It integrates NPN and PNP sections with built-in biasing resistors (R1=2.2kΩ, R2=47kΩ). Maximum ratings include a supply voltage of 50V and output current of 100mA per section. Total power dissipation is 300mW at 25°C. Operating temperature ranges from -55°C to +150°C. The device features epitaxial planar die construction and complies with RoHS standards.

Feature Summary

Procurement Notes

Verify the obsolete status of this part number before procurement planning. Confirm availability through authorized distributors or Diodes Incorporated directly. Check for alternative active series members if long-term supply is required. Ensure compliance with automotive quality standards if applicable to the end application.

Selection Notes

Select based on required resistor values (2.2kΩ input, 47kΩ base) and current handling capabilities. Consider the SOT26 package size for space-constrained designs. Verify thermal management requirements given the 300mW total power dissipation limit. Ensure voltage ratings meet the system's maximum supply conditions.

Part Context

This component belongs to the DCX(XXXX)K series of dual complementary pre-biased transistors. It shares the same SOT26 package and general electrical characteristics as other members like DCX124EK and DCX144EK, differing primarily in internal resistor configurations. The series is designed for compact digital switching applications.

Replacement Considerations

DCX123JU-7-F: Similar function but different package (SOT-363). DCX123JH-7: Similar function but different package (SOT-563). Verify pinout compatibility and resistor values when substituting.
